What is The Longevity Collective?
The Longevity Collective is a longevity and wellness spa in Fairfax, California, at 771 Center Blvd. It runs more like a med spa than a traditional medical office: alongside peptide therapy, it offers red light therapy, sauna and cold plunge, mild hyperbaric oxygen therapy, PEMF, cranial therapy, Somadome meditation, and a broader anti-aging program that includes services like acoustic soundwave therapy. Peptide therapy is prescribed by David Baldini, MD, whose career in medicine, in the clinic's own words, "spans four decades as an Emergency Room physician." No specific peptides are named, only that he works with "targeted peptides that address your specific health goals or medical condition." The clinic is open seven days a week, with hours running until 7 PM most days and until 5 PM on Sunday.
What does it cost?
A Peptide Therapy Consult with Dr. Baldini is listed at $500. He also offers a Longevity Plan at $1,200 and a Sexual Health Assessment at $1,000. None of these prices state whether medication is included, and no separate price list is given for ongoing peptide protocols once a plan is built. The spa side of the business, sauna and cold plunge, red light therapy, HBOT, PEMF, is sold by the session or in packages with its own published pricing, and a tiered membership is available, though those terms are not listed and you're asked to call or text for details.
What should you ask before you book?
Ask whether the $500 consult fee is applied toward treatment or charged separately from it, and whether an ongoing peptide protocol is billed monthly, by the vial, or some other way. Ask whether the peptides Dr. Baldini uses are compounded or FDA-approved products, since neither is specified. Ask what follow-up visits or lab work cost beyond the initial consult, and what the cancellation terms are for a membership before signing one. If you'd rather not drive to Fairfax for every visit, ask whether any part of the peptide program can be handled by phone or video, since that is not addressed anywhere.
Who is it a good fit for?
This is a good fit for someone in or near Marin County who wants peptide therapy folded into a broader menu of recovery and anti-aging services, sauna, cold plunge, red light, HBOT, in one location, and who is willing to ask directly what the $500 consult and any follow-up plan actually include before booking.
